Extremely powerful anger that builds up inside, and you constantly want to release it, but when you do, it unleashes a full wrath that might cause the biggest calamity that had ever existed... or
When you are
pissed off at someone or something, that means that you are angry or frustrated at him/her/them/it for
whatever he/she/they/it did to you, and you want to get revenge on him/her/them/it.
In other words, you are
mad. I mean, really? Do you really need to look this up? Come on! Seriously?
-Seeing that son of a bitch who stole my ipod walk by me really pisses me off.
-Ow! Damn it! This stupid
screw punctured my finger, Ahh! This damn thing really
pissed me off.
But hey, it's better to be
pissed off than to be pissed on!
